. anism for such bundling-presses, whereby the power is thrown out andthe action of the press is arrested when the compression has reached acertain predetermined degree.

My improvements are particularly applicable to a double bundling-pressin which two bundles of sheets or signatures can be simultaneouslycompressed;. but my improvements may be applied effectively to a singlebundling-press.

My invention consists of novel features of construction and combinationsof elements for eflectively accomplishing the desired results, and inorder that my invention may be fully understood I will first describethe same with reference to the accompanying drawings and afterward pointout the novelty more particularly in the annexed claims.

In said drawings, Figure 1 is a plan View, on a large scale, of a doublebundling-press embodying my improvements, parts being broken away. Fig.2 is a side elevation of the same on a smaller scale. Fig. 3 is an endView of the same. verse sectional elevation taken on the line X X ofFig. 2 and looking in the direction indicated by the arrows, said viewshowing parts of the automatic tripping device. Fig. 5 is a face view ofone of the compressionheads. Fig. 6 is an edge view of the same.

The framework of my improved bundlingpress may be of any suitable formand construction to properly support the operative parts of themechanism. In constructing a double bundling-press such as shown in thedrawings and hereinafter described I prefer to form the frame of threeuprights 10, 11,

i and 12, suitably braced adjacent to their lower ends by tie-rods 13and 14. An end view of the frame or upright 10 is shown in Fig. 3, andit will be understood that the otheruprights 11 and 12 are ofsubstantially the same form, differing slightly in the shape Fig. 4 is adetail trans-- of their upper ends to adapt them to support thebundling-troughs, as indicated in Fig. 4.

The frame-pieces 10 and 11 are braced at the top by the brackets orpillow-blocks 15, in which the main power-shaft 16 is suitablyjournaled. Power-shaft 16 carries upon one end fly-wheel 17 andband-pulley 18, by which the press is operated. This power-shaft 16 alsocarries suitable gears and clutches for connecting it with thecompression-screw, as hereinafter explained.

Supported between the uprights 11 and 12 at their upper ends are twoparallel bundlingtroughs, each trough being formed of a series ofparallel rods or bars 20 or 21, said rods or bars being rigidly securedat their ends in any suitable manner to the frame parts so as to form arigid structure, including the two bundling-troughs. The bars 20 formone of the troughs and the bars 21 the other.

Arranged directly beneath each of the troughs is a square track-bar 22or 23, ex-

tending parallel with the trough-bars and.

serving the purpose of assisting in support? ing and steadying thecompression-heads of both of the bundling-troughs.

Each trough is provided with two compression-heads 25 26 and 25 26,between which the sheets or signatures are compressed by the action ofthe machine. pression-head is formed in its compressionface with theintersecting slots 27 and 27, which expand interiorly into circularenlargements to facilitate the operation of passing the binding-cordsaround the bundles. The compression-heads are also each formed withgrooves 28 in their edges to fit upon the trough rods or bars 20 21 andwith integral downwardly-projecting ribs or flanges 29. The rib orflange 29 of each compression-head rests upon the upper face of one ofthe trackbars 22 23, so as to assist in supporting the trough-head inits angular position in the trough and at the same time provide a guidealong which the rib or flange slides when the compression-head is moved.

; The compression-heads 25 and 25, arranged one in each ofxthebundling-troughs, are independent of each other. These heads 25 and 25rest normally against compressionsprings 30, which are supported inholes or pockets 31, drilled into the inner face of the frame-upright11. Rods or bolts 25 project from the heads 25 25 through openings inthe upright 1 1 and have nuts on their ends to confine the heads inposition. Thevsprings. a

normally support the compression-heads 25 and 25 a slight distance awayfrom the face of the upright 11, the springs being of sufficientstrength to withstand the degree of compression which it is desired toapply to the bundles placed under compression. When the limit of thestrength of the springs is reached in the compressing operation of themachine, said springs will yield and be compressed, so as to allow theheads 25 and 25 to independently approach the face of the upright 11,with the result that either one or bothof said heads will actuate thetripping mechanism for disconnecting the power and stopping thecompression of the bundles. This tripping mechanism will hereinafter befully explained.

The other of the compression-heads 26 and 26,, which may be called thetraveling compression-heads, are united into an integral rigid structureby means of a bridging portion 35, which extends between the two heads,as shown in Fig. 1 of the drawings. This bridging portion connectsadjacent corners of the heads 26 and 26, forming, in effect, .a compoundhead, the two portions of which are adapted to operate in unison tocompress the bundles in both troughs simultaneously.

is the compression-screw, which is suitably journaled adjacent to itsopposite ends in bearings formed in the upper parts of theframe-uprights 11 and 12, one bearing being This comshown at 41 and theother at 42. pression-screw 40 is threaded through a suitable nut 43,rigidly secured in the suitable opening extending through the bridgingor connectingportion 35 of the connected compression-heads, so that therotation of the screw willcause the two traveling compression-heads tomove in the parallel troughs as a single structure.

Within the bearing 42 of the upright 11 the screw 40 is provided with athrust-bearing collar 45, which is shrunk or otherwise securely fastenedto the screw, so as to rotate with the screw in the bearing-socket ofthe frame. A capping-plate 46 of ring form surrounds the screw 40 and issecurely fastened within the recess 47 against the inner face of theupright 11 by means of bolts 48, so as to securely confine thethrust-bearing collar in its bearing-socket, and thereby efi ectivelyprevent the longitudinal displacement of the screw 40.

50 is a bevel-gear keyed to the power end of the screw 40.. This gear 50is in constant mesh with two similar bevel-gears 51 and 52, which areloosely journaled upon the powershaft 16, above referred to, each gear51 and 52 being arranged adjacent to one of the shaft-bearings 15.

Combined with each of theloosely-mount- I ed gears 51 and 52 is afriction band-clutch of ordinary construction, the rim portion 53 or 54of each clutch being formed integral with or rigidly attached to one ofthe gearwheels, while the expansible band portion of each clutch iskeyed to the power-shaft and carries the usual pivoted rock-arm 55,which is adapted to be engaged by one of the conical ends of the doubleclutch-spool 56. This clutch-spool 56 is suitably mounted upon thepower-shaft 16 and is capable of sliding longitudinally upon said shaftin either direction to actuate either clutch so as to lock either of thebevel-gears 51 or 52 upon the powershaft. This double clutch-spool 56 isformed with an annular groove 57, (indicated by dotted lines in Fig. 3,)in which engages the forked lower end of the actuating-arm 58, said arm58 having an offset 59 formed with atransvers'e cylindrical socketwhichfits upon a supporting-rod 60. The sockete'd offset 59 is securelyfastened upon the rod 60, so as to move with said rod. The rod 60 ismounted to slide in bearings 61, formed in the upper ends ofbracket-arms 62, which project up from the pillow-blocks 15. Theportions of the rod 60 adjacent to its ends which slide in bearings 61are provided with splines or feathers 63, which operateinfea-ther-grooves within the bearings to prevent the rotary shifting ofthe rod and to allow the longitudinal shifting of the rod to carry theclutch spool in either direction.

Surrounding the rod 60 between the offset 59 of the spool-actuating forkand each of the bearings 61 is an expansion spiral spring 64, whichsprings tend to resist the movement of rod 60 and of the connectedactuating-fork, in either direction and serve the purpose of returningsaid parts to their central inactive position for maintaining bothclutches in dis engaged condition, normally allowing both loose gears 51and 52 to remain at rest upon the rotating powershaft. 65 is ahand-lever j ournaled at 66 upon the upper end ofan upright bracket 67,which is secured to the upper edge of the frame-upright 10. Thishandlever 65 has a short longitudinal slot 68, into which projects thepin 69, formed upon the upper end of the spool-actuating fork-arm 58. Bymeans of the hand-lever 65 the spool 56 can be shifted in eitherdirection against the action of one of the compression-springs 64.

Mounted upon the projecting end of the rod 60 at the left of the pressisa-collar or tappet 7 O, which is adapted to coact with the latch ofthe automatic tripping -mechanism, presently to be described, for thepurpose of holding the clutch-operating mechanism in either of itsshifted positions until released I 'by the action of the machine.

The automatic tripping mechanism will now be described. 75 is alatching-lever .mounted upon a short shaft' 76, journaled upon a'bracket77 at the left-hand side of the machine. This latching-lever 75 has ahan dle portion 75 formed at its upper end, so

as to afford convenient means for its manual operation toreleasethemechanism in case of necessity. Depending from the short shaft 76 is arock-arm 7 8 ,Lcarrying at its lowerend a pin .79, which engages in anannular groove formed in a tappet-collar 81, secured to the projectingend of a tripping-rod 82. Tripping-rod 82 passes freely through anopening in the central'frame-upright 11 and extends to the rear of themachine adjacent to the endupright 12.. Secured .to the end of thetripping-rod 82 is a tappet-nut 83. Bolted to the rearface of thetraveling compressionhead- 26 is a downwardlyrojecting forkedtappet-plate 83", arrange to straddle the tr1pping-rod'82, so that whenthe compressionehead' 26 reaches the end of its return stroke .aftercompressing the bundle said forkedtappet-plate 83" will engage thetappet-nut'83 and'move'the rod 82 rearwardly to actuate thelatching-lever, as hereinafter explained. Between the tappet-collar 81and the frame-upright 11. an expansion spiral spring 84 is confined onthe rod 82, so as to give said rod a normal spring tendency to moveforwardly and cause latching-lever 75 to move upwardly into engagementwith tappet collar 70. The latchinglever 75 is formed with an arm oroffset 85, to which is pivoted at 86 a thrust-arm 87, formed with adownwardly-projecting portion 88, terminating in a cylindrical collar89, mounted upon a trip-rod 90. The collar 89 is confined upon rod 90 bymeans of nuts 91. Trip-rod 90 passes freely through a suitable openingformed in the upper abutment portion of the central frame-u right 11,its inner end projecting slightly beyond the face of the abutment in thepath of the compression-head 25, so that in the operation of compressinga bundle the movement of head 25 toward its abutment will engage thetrip-rod 90 and force it rearwardly, causing the latching-lever 75 to bedisengaged from the tappet upon rod 60.

The tripping mechanism so far described is suitable for a bundling-presshaving a single bundling-trough. It will be clear that in a doublebundling-press it is impracticable to quickly supply exactly the sameuantity of sheets or signatures to both of t e bundling-troughs, so thatit' is desirable to provide an additional tripping device forcontrolling the throW-out from the second bundlingpressthat is, twoindependent tripping devices, one actuated by each of the bundles beingformed. In my improved machinejI provide such independent trippingdevices in the mannerin whichIwill now explain Extending across themachine is a rock-shaft 95, journaled at its ends in suitable brackets96, securedto the top of the central frame-upright 11. This rock-shaft95 carries at one end a depending rock-arm 97, which rests behind pin98, projecting latthe opposite end of the rock-shaft 95 is a dependingrock-arm 99, carrying an eyebolt .100, which is confined upon a trip-rod101 by means of suitable nuts. The tappet-rod 101 projects through theabutment portions of the frame-upright 1.1 into the path of thecompression-head .25, with the result that when the bundle is beincompressed against the head 25 reaches the desired degree of compressionthe springs 30, sustaining said head, will yield and allow the head toengage the trip-rod 101 to cause it to rock the shaft 95, with theresult that the latching-lever will be actuated to release the clutch.By this means I provide a double bundling-press with a tripping deviceactuated by the thicker of the two bundles being formed.

The operation of the machine will be clear from the brief descriptionfollowing. The

power-shaft is continually rotated, the,

clutch-spool being normally in central disengaged position to allow bothgears 51 and 52 to remain at rest. Under these conditions thecompression-screw is also at rest. The compression-heads being in theirseparated position, the two troughs are filled With sheets or signaturesthat are to be compressed into bundles. A sufiicient quantity of sheetsor signatures are placed in each trough to practically fill the spacebetween the compression-heads. The hand-lever 65 is then pushed to theright for locking the gear 51 upon the power-shaft, with the result thatcompression-screw 40 'will be rotated to move the heads 26 and 26forward in the parallel troughs. It will be observed that in theposition of the parts shown in Fig. 2 the latching-lever 75 is held-awayfrom the latching-tappet 70 by reason of the engagement of thetappet-plate 83 with the tappetnut 83. In starting the machine it isnecessary for the operator to hold onto the starting-lever 65 for aninstant to allow head 26 to move tappet-plate 83 from engagement withnut 83, which. disengagement releases the tripping-rod 82 and its spring84, moves it forwardly, and causes the latching-lever 75 to engage theouter end or face of the tappet 7 O. The result of this engagement isthe locking of the operating mechanism in shifted position.

hold upon the lever 65. The compression screw 40 will continue to rotateand force the connected heads 26 and 26 toward the compression-heads 25and 25 until one of the heads 25 or 25 is forced inwardly against theabutment of upright 1.1, overcomingthe resistance of springs 30 andactuating one of the trip-rods 90 or 101 for forcing the latching-lever75 out of engagement with the tappet 7 0. The moment lever 75 isdisengaged from tappet 70 the right hand spring 64 will force rod 60 andconnected spool v56 to the left for releasing the bevel-gear 51 from theThe operator may then release his power shatt and ar'resting theadvancing action of the compression-screw. The operator then ties thebundles by passing cords around them through the armholes of thecompressioneheads in the well-known man As soon as the bundles have beenver'7'5 engagesth'e inner-face of tappet for holding the operatingmechanism in its lefthand shiftedxposition. As soon as the latchisengaged the operator may release hishold on the lever, andthecompression-screw will continue to rotate 1n'1ts reversedlrection tocause the connected heads 26 and 26 to re.

turn to. their normal positions, it beingund erstood that when theconnected heads reach their return positionthe-tappet 83 willengage. thetappetenut 83 and shift the tripping rod 82 to againdisengage thelatching-lever fromthe tappet 7 O to-allowthe left-hand spring 64 toreturn the clutch-operating parts to their normalicentral inoperativeposition. The machine is then-ready for a repeti tion of. the describedoperation.

:It will be observedthat the clutch which locksithe gear 52 to thepower-shaft isbroader and stronger than the corresponding clutch, whichlooks gear 51 .to the powershaft. This is for the purpose of insuringsufiicient power for releasing the compression-heads after the'bundleshave been. compressed.
